The main material of high hardness end mills is tungsten steel, also known as cemented carbide. Cemented carbide is mainly composed of carbide (WC, TiC) micron powder of high hardness refractory metal, with cobalt (Co) or nickel ( Ni) and molybdenum (Mo) are used as binders, and the product material of high-hardness end mills is a powder metallurgy product made of tungsten steel sintered in a vacuum furnace or a hydrogen reduction furnace. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500 °C , still has high hardness at 1000℃. Carbide is widely used as materials, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and high hardness end mills are also used. It can be used to cut hard-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel and tool steel.
Now the cutting speed of new cemented carbide is hundreds of times that of carbon steel. Cemented carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasives, cylinder linings, precision bearings , nozzles, etc.
